Maybe. It could just be a regular Fenring, but by the looks of the room it's in and those runes in the first image it looks like Iron Gate are going to be giving Fenrings a lot more attention in coming updates. I for one would not mind at all if Fenrings got a major buff to be more in line with the mini-bosses from the Black Forest and Swamp (Trolls and Abominations). Although the mountains do already have the golems which do seem to scale properly to the other mini-bosses in terms of challenge. But I still don't mind at all that the Fenrings are getting some love; they're awesome.
